AZTEC, N.M. (AP) – Authorities are responding to a shooting at a high school in northwest New Mexico.

Deputies with the San Juan County Sheriff’s Office told reporters that a suspect was in custody but they did not release any other information.

Sheriff Ken Christesen confirms the shooting at Aztec High School on Thursday morning. He did not say whether anyone had been injured or killed.

The school is in the Four Corners region and is near the Navajo Nation.

Authorities say the school was placed on lockdown and evacuated. Other schools in the area were also locked down, and authorities were setting up staging areas where parents could gather and wait for more information.
